[0002] Humidifiers have become a common household appliance, with common types including ultrasonic humidifiers and evaporative humidifiers. Evaporative humidifiers use a wet curtain to increase the effective evaporation area of ​​water, and with the help of a fan, they can achieve higher humidification efficiency.

[0003] In related technologies, especially for a ring-shaped wet curtain body, the water-sprinkling component at the top of the wet curtain body is set as a ring-shaped water tank with multiple water outlets at the bottom of the water tank. The water tank has a water inlet. The water flow rate dripping onto the wet curtain body is large at the water outlets near the water inlet, while the water flow rate dripping onto the wet curtain body is small at the water outlets far from the water inlet.

[0004] This results in significant differences in the amount of water dripping onto different parts of the circumference of the wet curtain body, leading to uneven water distribution. Utility Model Content

[0042] In related technologies, especially for evaporative cooling pads arranged in a ring, the water distribution component at the top of the cooling pad is a ring-shaped water trough with multiple drain outlets at the bottom. The trough has one water inlet. The water flow rate is high at the drain outlets near the inlet, while the water flow rate is low at the drain outlets further away from the inlet. This results in significant differences in the amount of water dripping onto the cooling pad around its circumference, leading to uneven water distribution.

[0043] This utility model proposes a water distribution plate.

[0044] Please see Figure 1In one embodiment of this utility model, the water distribution plate 100 is used in a humidifier. The water distribution plate 100 includes a plate body 1. An air outlet 11 is formed in the middle of the plate body 1, which is arranged vertically. A plurality of water distribution grooves 12 are formed on the upper side of the plate body 1, which are spaced apart along its circumference, to correspond to the upper side of a plurality of block-shaped curtain cores 210 spliced ​​along its circumference on the humidifier. Each water distribution groove 12 is provided with a water outlet 13 and a water inlet 14, which are used to input water for humidification into each water distribution groove 12.

[0045] In the technical solution of this utility model, the water distribution plate 100 has an air vent 11 in its body 1, through which air flows. The air vent 11 in the middle allows air to pass through. The body 1 is arranged in a ring shape and is placed on the upper side of multiple curtain cores 210 spliced ​​together circumferentially. The water distribution plate 100 is arranged in multiple water distribution grooves 12 at intervals along the circumference, so that each water distribution groove 12 corresponds to a curtain core 210. A water distribution port 13 is provided at the bottom of the water distribution groove 12, and a water inlet 14 is also provided in the water distribution groove 12. The water source for humidification enters the water distribution groove 12 from the water inlet 14, and then drips onto the curtain core 210 through the water distribution port 13. Each water distribution tank 12 can be supplied with water through the water inlet 14, ensuring that each tank has sufficient water to drip onto its corresponding curtain core 210. This ensures that the amount of water dripping onto each curtain core 210 is equal, and that the water dripping from the evaporative cooling pad 200 is uniform across its circumference, thus solving the problem of uneven water distribution. Furthermore, since each water distribution tank 12 is relatively independent, water can be supplied to different numbers of tanks 12, allowing water to flow across different numbers of curtain cores 210, thereby adjusting the humidifier's effect on increasing air humidity. Generally, for multiple water distribution tanks 12, the bottom area of ​​each tank is equal, and the number and position of the water outlets 13 at the bottom are also equal, ensuring that the water distribution effect of each tank 12 dripping onto its corresponding curtain core 210 is the same. The water distribution tray 100 (i.e., the water distribution tank 12) can hold a certain volume of water. The structure of the water distribution plate 100 is not limited; it can be a trough-shaped structure with an open top or a closed structure composed of a bottom box and a top cover.

[0046] Since the curtain core 210 has a length in the circumferential direction of the disc body 1 and a width in the width direction of the disc body 1, the width direction of the disc body 1 is from the center position to the outer edge position. The more evenly the water drips onto the curtain core 210, the better the water evaporation effect and the corresponding humidification effect. Therefore, each of the water distribution channels 12 is provided with multiple water distribution outlets 13, so that water drips from multiple water distribution outlets 13 to various parts of the curtain core 210. In order to prevent multiple water distribution outlets 13 from being concentrated and unevenly distributed, multiple water distribution outlets 13 are distributed along the circumferential direction of the disc body 1, so that the water drips onto the curtain core 210 evenly in the circumferential direction. Alternatively, multiple water distribution outlets 13 can be distributed along the width direction of the disc body 1, so that the water drips onto the curtain core 210 evenly in the circumferential direction and the width direction. Multiple water outlets 13 can also be distributed along the circumference of the disc body 1 and along the width of the disc body 1, so that the multiple water outlets 13 are arranged in an array, making the water dripping onto the curtain core 210 more uniform.

[0047] For the same water distribution tank 12, there are multiple water outlets 13 and one water inlet 14. When water is injected into the water inlet 14, water droplets will preferentially drip from the water outlet 13 closest to the water inlet 14. However, at this time, the drainage flow rate of the water outlet 13 is less than the water inlet flow rate of the water inlet 14. Since the plate 1 is divided into multiple smaller water distribution tanks 12, the injected water can quickly cover the bottom of the water distribution tank 12, so that multiple water outlets 13 drain water at the same time, and the water can drip evenly. At this time, the drainage flow rate of the water outlet 13 is equal to the water inlet flow rate of the water inlet 14, and the water volume inside the water distribution tank 12 reaches balance.

[0048] Since the evaporative cooling pad assembly 1000 is composed of multiple components, to ensure installation stability and relative positional relationships with other components, the disc body 1 needs to be fixedly connected to the humidifier bracket 300. The curtain core 210 is confined within the installation area 15 defined by the disc body 1 and the bracket 300, thereby ensuring the stability of the evaporative cooling pad assembly 1000. Specifically, the disc body 1 also includes an installation area 15 located between the ends of two adjacent water distribution channels 12. The installation area 15 is provided with an installation part 151, which is used to install with the humidifier bracket 300. The installation part 151 can be a threaded hole running vertically through the humidifier, fixedly connected to the bracket 300 using a stud; or it can be one of a locking post or a locking groove, with the other located on the bracket 300 and snapped together. Specific connection methods are not limited here.

[0049] To facilitate the injection of water into the multiple water distribution tanks 12, multiple water inlets 14 are centrally located. Each water distribution tank 12 has an inner sidewall near the center of the disc body 1 and an outer sidewall opposite to the inner sidewall; the water inlets 14 are located on the inner sidewall. That is, the water inlets 14 are positioned facing the air vent 11. The water delivery assembly 220 for introducing water into the multiple water distribution tanks 12 can be located inside the air vent 11 and communicate with the multiple water inlets 14. The volume of the water delivery assembly 220 is installed inside the disc body 1 and is smaller than the area corresponding to the air vent 11. If the water inlets 14 are located on the outer sidewall, the water delivery assembly 220 would need to extend at least partially outside the disc body 1 to communicate with the water inlets 14, and its volume would be larger than the area corresponding to the disc body 1. Therefore, by placing the water inlets 14 on the inner sidewall, the structure of the water delivery assembly 220 is smaller, and the corresponding humidifier structure is also smaller.

[0050] This utility model also proposes a wet curtain assembly 1000, please refer to [link / reference]. Figure 2 and Figure 3 The evaporative cooling pad assembly 1000 includes an evaporative cooling pad body 200 and a water distribution tray 100. The specific structure of the water distribution tray 100 is as described in the above embodiments. Since the evaporative cooling pad assembly 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The evaporative cooling pad assembly 1000 includes a water distribution tray 100 and an evaporative cooling pad body 200. The evaporative cooling pad body 200 includes a plurality of curtain cores 210 arranged at intervals along the circumference. Each curtain core 210 is block-shaped and the plurality of curtain cores 210 together define an air passage 213 that is open at least at the top. The side surface of each curtain core 210 forms a plurality of air inlet channels 215 that communicate with the air passage 213. The water distribution tray 100 is disposed on the upper side of the evaporative cooling pad body 200, and the plurality of water distribution grooves 12 are correspondingly disposed with the plurality of curtain cores 210 in the vertical direction.

[0051] In this evaporative cooling pad assembly 1000, the multiple curtain cores 210 are arranged in a circular cylindrical structure. Air outside the cylindrical structure enters the interior of the cylindrical structure (i.e., the air passage 213) through the air inlet channel 215 of the curtain core 210. The upper end of the air passage 213 is connected to the air outlet 11, and the gas is discharged through the air outlet 11. Since the water distribution plate 100 is located above the curtain core 210, water droplets flow off the surface of the curtain core 210 under the action of gravity. When the gas passes through the curtain core 210, it evaporates the moisture on the surface of the curtain core 210, causing the liquid water to evaporate into water mist, thereby achieving a humidification effect.

[0052] Please see Figures 4 to 6To ensure the water-guiding effect of the curtain core 210, the curtain core 210 includes a support structure 211 and an evaporation assembly 212. The support structure 211 includes at least two support portions 2111 spaced apart in the horizontal direction. The evaporation assembly 212 is located between the two support portions 2111 and includes multiple evaporation plates 2121 arranged at intervals in the vertical direction. An air inlet channel 215 is defined between two adjacent evaporation plates 2121 in the vertical direction. Each evaporation plate 2121 is provided with a water passage 216, or a water passage 216 is formed between each evaporation plate 2121 and the support portion 2111. The support portion 2111 supports the evaporation plates 2121, and the evaporation plates 2121 increase the evaporation area. The air inlet channel 215 is formed between two adjacent evaporation plates 2121 in the vertical direction, allowing air to fully contact the water on the surface of the evaporation plates 2121 when it passes through the air inlet channel 215. The water passage 216 facilitates the flow of water from the upper evaporation plate 2121 to the lower layer.

[0053] To ensure that water can cover the evaporation surface, each of the evaporation plates 2121 is inclined downwards near the water passage 216. This allows the water to flow under gravity, moving along the inclined direction of the evaporation plates 2121, thus covering the evaporation surface and increasing the evaporation area. The thickness of the evaporation plates 2121 needs to be at least 5mm thick to ensure sufficient strength to resist damage, while also allowing for adequate airflow and accommodating a large number of evaporation plates 2121. Therefore, the thickness of the evaporation plates 2121 should be at least 20mm.

[0054] To ensure water is distributed across the evaporator plates 2121 and achieve a larger evaporation area, multiple evaporator plates 2121 include adjacent first and second evaporator plates 2121. The first and second evaporator plates 2121 are tilted in opposite directions, such that the lower end of the first evaporator plate 2121 corresponds to the upper end of the second evaporator plate 2121. Water droplets flow from the upper end of the first evaporator plate 2121 to its lower end, and then drip onto the upper end of the second evaporator plate 2121. The number of evaporator plates 2121 includes, but is not limited to, two. The positional relationship between the first and second evaporator plates 2121 refers to the relative positional relationship between any pair of adjacent evaporator plates 2121, thus preventing water droplets from flowing over only a few evaporator plates 2121 and dripping into the water tank, ensuring that each evaporator plate 2121 can effectively perform evaporation.

[0055] For the same curtain core 210, in order to have a larger evaporation area, multiple support parts 2111 are provided, and an installation channel 214 is defined between each two adjacent support parts 2111; therefore, there are multiple installation channels 214. Multiple evaporator groups 212 are also provided, distributed in multiple installation channels 214. The air inlet channel 215 is defined by the wall surface of two adjacent evaporator plates 2121 in the vertical direction and the corresponding installation channel 214. Multiple air inlet channels 215 are included in the same installation channel 214. For the arrangement of multiple water outlets 13 in the same water distribution tank 12, the multiple water outlets 13 are distributed circumferentially to ensure that each installation channel 214 has a corresponding water outlet 13, and that each evaporator plate 2121 in each installation channel 214 can be coated with moisture. Multiple water inlets 13 are also spaced along the width of the plate 1. This is so that there are multiple water inlets 13 corresponding to the same installation channel 214. The arrangement direction of the multiple water inlets 13 corresponds to the length direction of the evaporator plate 2121, so that the extension direction of one side of the upper end of the evaporator plate 2121 is the length direction, thus making the water droplets fall evenly on the evaporator plate 2121.

[0056] To allow water to drip from the upper evaporator plate 2121 onto the lower evaporator plate 2121, at least partially, one end of the evaporator plate 2121 has a gap with the support portion 2111, defining a water passage 216 between them. Two adjacent water passages 216 in the vertical direction are staggered. The water passage 216 is positioned along one side of the length of the evaporator plate 2121, not in the middle, which facilitates demolding during injection molding of the core 210. If the water passage 216 were positioned in the middle of the evaporator plate 2121, demolding would be impossible, making injection molding impossible and increasing the production cost of the core 210.

[0057] In one embodiment, the curtain core 210 in the prior art is generally made of materials such as spunlace fabric, 3D fiber fabric, or corrugated paper. Due to their inherent characteristics, they are difficult to clean and maintain, have a short service life, require regular replacement, and are costly. Furthermore, after absorbing water, bacteria easily grow on the surface, producing odors, which affects user health and experience. Therefore, the material of the wet curtain body 200 is selected to be a water-resistant material, such as plastic or other rigid materials, allowing each curtain core 210 to be removed for rinsing and cleaning. This design not only extends the service life of the curtain core 210 but also allows for cleaning, restoring the curtain core 210 to a clean state and preventing odors. However, because water-resistant materials lack sufficient hydrophilicity, the evaporation time is short and the evaporation area is small, which can affect the evaporation effect. Therefore, a hydrophilic coating is provided on the surface of the curtain core 210. This facilitates water spreading on the surface of the wet curtain body 200, reduces the rate of water dripping, and improves humidification performance. The hydrophilic coating can be applied to the surface of the support structure 211 and the evaporation plate 2121, and can be achieved by attaching hydrophilic materials or by electrostatic flocking.

[0058] Water that does not evaporate after flowing through the curtain core 210 drips into a water tank below the curtain core 210. The water in the tank is then transported to the water distribution tray 100 by the water supply assembly 220. Specifically, the evaporative cooling pad assembly 1000 also includes a water supply assembly 220, which includes a water pipe 221. The water pipe 221 has a water inlet 2211 and multiple drain outlets 2212. The water inlet 2211 is placed inside the water tank of the humidifier, and the multiple drain outlets 2212 are respectively connected to multiple water inlets 14. Opening and closing mechanisms are provided at the locations of the multiple drain outlets 2212 to control the connection and disconnection between the drain outlets 2212 and the water inlets 14, thereby controlling the number of curtain cores 210 that will be sprayed with water, and thus adjusting the humidification level.

[0059] This utility model also proposes a humidifier, which includes: a housing, a wet curtain assembly 1000, a water tank, and a fan assembly; the housing has an air inlet and an air outlet, and a ventilation channel connecting the air inlet and the air outlet; the wet curtain assembly 1000 is disposed in the ventilation channel and installed corresponding to the air inlet, such that the air inlet channel 215 is connected to the air inlet, and the upper end of the air passage 213 is connected to the air outlet; and the water tank is disposed in the housing and located in the... Below the evaporative cooling pad assembly 1000, the water tank is used to guide water through the water supply assembly 220 to the upper end of the evaporative cooling pad assembly 1000, and the water tank is used to receive water flowing down through the evaporative cooling pad assembly 1000; the fan assembly is located in the ventilation channel and at the upper end of the evaporative cooling pad assembly 1000, and the fan assembly is used to drive airflow from the air inlet to flow sequentially through the air inlet channel 215, the air passage channel 213, and the air outlet 11, and to the air outlet.

[0060] Specifically, the humidifier also includes a housing, a fan assembly, and a water tank. The housing has an air inlet and an air outlet 11, as well as a ventilation channel connecting the air inlet and the air outlet 11. Specifically, an air inlet is provided on the side surface of the housing, and an air outlet 11 is provided on the top of the housing. The inner cavity of the housing forms a ventilation channel. The fan assembly and the evaporative cooling pad assembly 1000 are both located inside the housing and within the ventilation channel. The evaporative cooling pad assembly 1000 is located below the fan assembly. The water tank is located inside the housing and below the evaporative cooling pad assembly 1000. The water tank is used to guide water through the water supply assembly 220 to the water distribution tray 100 at the upper end of the evaporative cooling pad assembly 1000. The water tank is used to receive water flowing down through the evaporative cooling pad assembly 1000. The fan assembly is used to drive the airflow from the air inlet to the air outlet. This allows external air to enter the air passage 213 through the air inlet of the housing and the air inlet channel 215 of each curtain core 210, then gather in the ventilation channel, and finally be discharged through the air outlet 11 of the housing.
